When a product of uncertain quality is first introduced, consumers may be enticed to strategically delay their purchasing decisions in anticipation of the product reviews of their peers. This paper investigates how the presence of social learning interacts with the adoption decisions of strategic consumers and the dynamicpricing decisions of a monopolist firm, within a simple two-period model. ...

It is probably no exaggeration to say that few obstetricians have a very clear perception of the progress of events, normal and pathological, during ante-natal life. The drama of embryonic and fcetal development and growth is going on, but the curtain has not been rung up, and the spectators get only confused impression's from the swaying of the drop-scene and from vague sounds, " excursions an...

We study a definition of subjective beliefs applicable to preferences that allow for the perception of ambiguity, and provide a characterization of such beliefs in terms of market behavior. Using this definition, we derive necessary and sufficient conditions for the efficiency of ex ante trade and show that these conditions follow from the fundamental welfare theorems. When aggregate uncertaint...

PROFUSE heemorrhage occuring prior to, or shortly after, the birth of a child, is always a dangerous, and often a fatal, complication, although with proper diagnosis and treatment the maternal death rate should be very low. Practically all varieties of ante-partum hemorrhage, with the exception of those originating from lacerations of the genital tract, are due to a partial separation of the pl...

The free website laun...

1 In an exam-based school choice matching mechanism (e.g., China’s college admission), student exam scores are used to determine school priorities. However, a student’s true qualifications or ability may not be perfectly revealed by his/her exam score. The matching outcome can thus be undesirable in the sense that it is not ex-ante fair, i.e., it may not match students with higher intrinsic abi...

In a patent thicket licensing provides a mechanism to either avoid or resolve hold up. We study the choice between ex ante licensing to avoid hold up and ex post licensing to resolve it. Firms’ choice of licensing contract is studied in the context of a patent portfolio race. We show that high expected blocking leads to ex ante licensing while ex post licensing arises if expected blocking is lo...

An extension of the standard rationing model is introduced. Agents are not only identified by their respective claims on some amount of a scarce resource, but also by some exogenous ex-ante conditions (characteristics), different from claims (e.g., endowments, entitlements, wealth, obligations, assets). Inequalities in the ex-ante conditions induce compensations between agents which influence t...
